Magnetic capacitance

''Magnetic capacitance (capacitive magnetic reactance)'' (SI Unit: -Ω−1) is a magnetic "reactance" which prevents magnetic "current" in oscillating magnetic circuits from rising. This is associated with high reluctance.
For harmonic regimes it is equal to:
:x_C = \frac
Where:
:C_M is the magnetic capacitivity (SI Unit: -s·Ω−1)
:\omega is the angular frequency of the magnetic circuit
In complex form it is written as an imaginary number:
:-jx_C = -j\frac = \frac
The electrical potential energy sustained by magnetic capacitivity varies with the frequency of oscillations in magnetic fields. The average power in a given period is equal to zero. The magnetic capacitance is a reactive part of the magnetic circuit.〔Pohl R. W. ELEKTRIZITÄTSLEHRE. – Berlin-Gottingen-Heidelberg: SPRINGER-VERLAG, 1960.〕〔Popov V. P. The Principles of Theory of Circuits. – M.: Higher School, 1985, 496 p. (In Russian).〕
